I 'm also sad about this situation of efforts done in parallel of upstream 
projects. If Kurt wants to integrate his tests for the PROJ part using GTest, 
I'm happy with that, but that should be done quickly before I have too many 
catch2 tests written. In the PROJ context, that would mean having both a 
automake and cmake way of building GTest (probably GTest minimum code & 
headers integrated in proj source tree for conveniency ?). I'm not really 
confortable enough with build systems to do such an effort for a test
